POST-запрос для загрузки файла.

Существует три способа загрузки файлов через API:

  1. Прямая загрузка локального файла
  2. Загрузка копии файла с URL-адреса
  3. Загрузка локального файла кусками

Все эти методы требуют учетной записи с правом upload.

Документация по API


action=upload

(main | upload)
  • This module requires read rights.
  • This module requires write rights.
  • This module only accepts POST requests.
  • Source: MediaWiki
  • License: GPL-2.0-or-later

Upload a file, or get the status of pending uploads.

Several methods are available:

  • Upload file contents directly, using the file parameter.
  • Upload the file in pieces, using the filesize, chunk, and offset parameters.
  • Have the MediaWiki server fetch a file from a URL, using the url parameter.
  • Complete an earlier upload that failed due to warnings, using the filekey parameter.

Note that the HTTP POST must be done as a file upload (i.e. using multipart/form-data) when sending the file.

Specific parameters:
Other general parameters are available.
filename

Target filename.

comment

Upload comment. Also used as the initial page text for new files if text is not specified.

Default: (empty)
tags

Change tags to apply to the upload log entry and file page revision.

Values (separate with | or alternative): convenient-discussions, possible vandalism, repeating characters
text

Initial page text for new files.

watch
Deprecated.

Watch the page.

Type: boolean (details)
watchlist

Unconditionally add or remove the page from the current user's watchlist, use preferences (ignored for bot users) or do not change watch.

One of the following values: nochange, preferences, watch
Default: preferences
watchlistexpiry

Watchlist expiry timestamp. Omit this parameter entirely to leave the current expiry unchanged.

Type: expiry (details)
ignorewarnings

Ignore any warnings.

Type: boolean (details)
file

File contents.

Must be posted as a file upload using multipart/form-data.
url

URL to fetch the file from.

filekey

Key that identifies a previous upload that was stashed temporarily.

sessionkey
Deprecated.

Same as filekey, maintained for backward compatibility.

stash

If set, the server will stash the file temporarily instead of adding it to the repository.

Type: boolean (details)
filesize

Filesize of entire upload.

Type: integer
The value must be between 0 and 5,368,709,120.
offset

Offset of chunk in bytes.

Type: integer
The value must be no less than 0.
chunk

Chunk contents.

Must be posted as a file upload using multipart/form-data.
async

Make potentially large file operations asynchronous when possible.

Type: boolean (details)
checkstatus

Only fetch the upload status for the given file key.

Type: boolean (details)
token

A "csrf" token retrieved from action=query&meta=tokens

This parameter is required.

Upload warnings

Note that an upload may fail due to a number of warning conditions. This can be overridden by setting ignorewarnings=1. Some notable warnings include:

  • exists: A file with the given name already exists. If this warning is ignored, the uploaded file will replace the existing file.
    • no-change: A file with the given name already exists and is exactly the same as the uploaded file.
    • duplicateversions: A file with the given name already exists and and old version of that file is exactly the same as the uploaded file.
  • was-deleted: a file with the given name used to exist but has been deleted.
  • duplicate: The uploaded file exists under a different (or the same) name. Uploading a duplicate may be undesirable.
  • duplicate-archive: The uploaded used to exist under a different (or the same) name but has been deleted. This may indicate that the file is inappropriate and should not be uploaded.
  • badfilename: The file name supplied is not acceptable on this wiki, for instance because it contains forbidden characters

Пример

Выполнение любого POST-запроса является многоэтапным процессом:

  1. Войдите, используя один из методов, описанных в API:Вход .
  2. Получите CSRF токен :


  3. Отправьте POST-запрос с токеном CSRF, чтобы загрузить файл.

Пример 1: Загрузка локального файла напрямую

При прямой загрузке файлов запрос должен использовать multipart/form-data в качестве Content-Type или enctype, application/x-www-form-urlencoded не будет работать.

Пример 3: Загрузка файла кусками

Поскольку загрузка огромного файла в одном HTTP POST может быть ненадёжной, API также поддерживает режим фрагментированной загрузки, в котором вы делаете несколько запросов с частями файла. Это доступно в MediaWiki версии 1.20 и выше, хотя до версии 1.25 SVG-файлы не могли быть загружены через фрагментированную загрузку. Это используется Расширение:UploadWizard в браузерах, поддерживающих FileAPI, загружая файлы кусками по 1 мегабайту, но вы можете выбрать свой собственный размер. Это работает в сочетании с режимом хранения (stash mode), чтобы собрать файл по частям, а затем зафиксировать его в конце.

Шаг 1: Передайте содержимое первого куска


Для всех кусков, кроме последнего, вы получите это:

Result 1
{
	"upload": {
		"offset": 5000,
		"result": "Continue",
		"filekey": "16gqn54g1z98.4g5brp.42588.jpg"
	}
}

Шаг 2: Передайте параметр filekey для второго и последующих кусков

До тех пор пока получаете параметр filekey из предыдущего ответа продолжения:


Для последнего куска вы получите это:

Дополнительная информация

  • Чтобы проверить состояние текущей загрузки в тайник или ход публикации файла из тайника, отправьте POST-запрос:
Результат
{
	"upload": {
		"stage": "uploading",
		"offset": 5000,
		"result": "Continue"
	}
}
  • Ниже приведен пример составного POST к /api.php?action=upload, представляющего один кусок. Обратите внимание, что вы должны достать файла из тайника, чтобы он появился в Вики, как только вы успешно загрузили все куски.
